In this picture (not a Marmot though), you'll see the draft tube. It's the long, black insulated tube that runs down the length of the zipper. In the foreground, you'll also see the green draft collar that insulates around your neck between the hood and the body of the bag. Both are important features to look for in quality mummy bag construction.

It insulates the zipper to help retain body heat.

It is that extra strip of material on the inside of the zipper that ensures that you do not have draft coming through the zipper area.
